Credit scoring models are the basis for financial institutions like
retail and consumer credit banks. The purpose of the models is to
evaluate the likelihood of credit applicants defaulting in order to
decide whether to grant them credit. The area under the receiver
operating characteristic (ROC) curve (AUC) is one of the most commonly
used measures to evaluate predictive performance in credit scoring. The
aim of this thesis is to benchmark different methods for building
scoring models in order to maximize the AUC. While this measure is used
to evaluate the predictive accuracy of the presented algorithms, the AUC
is especially introduced as direct optimization criterion.
